PILE-CUTTING MACHINE.

To all whom it may concern: i

Be it known thatI, ARTHUR MoRToN, of

yViarwick, in the county of Kent and State of Rhode Island, haveinvented certain new and useful Improvements in Pile-Cutting Machines;and I do hereby declare the following specification, taken in connectionwith the accompanying drawings, forming a part of the same, to be afull, clear, and exact description thereof.

The invention relates to a machine for cutting the race or pile of pilefabrics, such as velvets, corduroys, etc. o f that character in whichthe fabric is caused to travel past one or more knives in the form of anendless web, and more particularly toa machine of this characterespecially designed for cutting velvets. When the fabric is thus causedto travel through the machine in the form of an endless web, suchendless web is formed by uniting the ends of the fabric which result inthe formation of a seam or bunch at the point of union through which theknife cannot pass.

The object of the present invention is to provide means forautomatically stopping the machine and thus stopping thefeed of thefabric when the seam or bunch referred to approaches the knife.

In another application Serial No. 368,329, filed Apr. 15, 1907, I haveshown and described a pile-cutting machine of the character referred toprovided with an electrical stop-motion for automatically stopping themachine and the feed of the fabric as the seam or bunch referred toapproaches the knife. A mechanical stop-motion, if it can be madesufficiently sensitive and reliable to serve the purposes required, isin many respects preferable to an electric stop-motion, and for thereason that such mechanical stop-motion is necessarily simpler and lessliable to get out of order.

I have now succeeded in devising a mechanical stop-motion which issufliciently sensitive and reliable for automatically stopping themachine and the feed of the fabric when the seam or bunch referred toapproaches the knife, and the present invention consists primarily inthe combination with the other parts of the machine of devices,constituting a mechanical stop-motion,

Specification of Letters Patent.

Serial No. 368,330.

for automatically 'stopping the feed of the fabric when the seam orbunch referred to approaches the knife.

The invention further consists in the construction, combinations andarrangement of parts hereinafter described and claimed.

Referring to the drawings, Figure 1 is a side elevation of the left handside of a pilecutting machine embodying the invention. Fig. 2 is acorresponding side elevation on an enlarged scale of the forward end ofthe machine. Fig. 3 is an end elevation of the left hand end of Fig. 2.Fig. l is a corresponding side elevation of the right hand side of theforward portion of the machine. Fig. 5 is a front end elevation of Fig.4.

The machine comprises a suitable frame 1 in which the several operatingparts are mounted. The fabric travels through the machine in the form ofan endless web. The knife 2 is located at the front of the machine, andthe fabric 3, after the race has been cut, is carried down on to atraveling endless apron or lattice Il" at or near the bottom of themachine where it drops in folds, and in this form is carried by thetraveling apron to the rear of the machine.

From the apron at the rear of the machine the fabric is carried up overa feed-roll 5 and down an incline 6. At the foot of this incline thefabric turns upward and is carried over two fixed bars 7, 7, at the topof the frame. Preferably the fabric is left more or lessv loose at thepoint where its direction is changed from the foot of the inoline to thevertical. From the stationary bars 7, 7, the fabric travels down anotherincline 8 around an idler roll 9, up over a positively driven roll 10,preferably rubbercovered, down around another idler roll 11,

then forward around a tension roll 12, andl around the drag-roll 13,then under the knife 2, and around the feed-roll 14 and the tension-roll15, thence downward between a pair of supplemental feed-rolls 16, 17,the feedroll 16 being positively driven and thefeedroll 17 being anidler roll, and thence down on to the traveling apron l above referredto. Preferably a stationary bar 18 is arranged between the drag-roll 13and the feed-roll 14 in front of the free end of the knife for thepurpose of supporting the Patented J an. 10, 1911.A

lley 31 a belt 34 extends to a Vvstop the feed of the fabric.

fabric at or adjacent to the cutting point. This Supporting bar is madeadjustable toward and from the knife, vas shown in Fig. 1 The necessarytension. on the fabric at the cutting point is produced by means of Atherolls 13 and 14. The feed-roll 14 is positively driven, while thedrag-roll 13 is provided with a friction device to be hereinafterdescribed, whereby a friction or drag may be put on said roll. Y

The main driving-shaft 19 is provided with a pulley 20 driven by a belt21 from an; 'overhead countershaft. .end ofthe driving-shaft 19 is apulleyl 22 from which a belt 23 extends toma pulley 24 on the left handendv of the positively driven feed-roll14. On the driving-shaft 19, adjaeent to the main driving-pulley 20, is a pulleyv 25, from which a crossbelt` 26 extends to a loose pulley 27 on the drag` roll 13. The pulley27 is a two-step conepulley and from ythe smaller lstep of said pulley,a` belt 28 extends to a pulley 29 on the right hand end of thefeed-roll 14. The pulley 27 ony the drag-roll 13v is somewhat largerthan the pulleyj29 on the feed-roll 14, and so thatsaid pulley 27rotates at a slower speed than thepulley 29. -On the left hand end ofthe drag-roll 13 are two pulleys 30 and 31 shown in Fig. 1. From thepulley 30 a belt 32 extends around a pulley 33 on the left hand end ofthe driven vsupplemental feed-roll 16. From the pulu pulley 35 on theleft hand end of the driven roll 10. On the right hand end of said roll10 are two pulleys 36 and 37. From the pulley 36 a .belt 38 serves todrive the feedroll 5, while from the pulley 37 a belt 39 serves tooperate the endless apron 4.

' The pulley 22 on the driving-shaft 19 is `loose on said shaft, but isadapted to be connected with said shaft by a suitable clutchmechanism,preferably a friction-clutch, as vshown in the drawings. This clutch maybe of any desired construction and as it forms no part of the presentinvention, the detailed construction of the clutch shown need not bedescribed. It will be understood that when the pulley 22 is connectedwith the Vdriving-shaft 19, the fabric will. be fed vIn machines of thischaracter it is desirable that when the driving power is disconnectedfor t-he purpose of stopping the machine, the machine should be quicklybrought to a full stop, and so as to promptly j For this purpose abrake-mechanism is applied to some On the opposite part of thefeed-mechanism to quickly stop the f eed of the fabric whenever thedriving power is disconnected.

In the arrangement shown the brake is applied to the drag-roll 13, orrather to the pulley 30 on said roll. This brake may be of any suitableconstruction, and in the drawings is shown as comprising a pivotedbrake-slice 42, which is pivoted to the frame of the machine, and whichis designed to be forced into contact with the inner surface of theiange of the pulley 30 by means of a coiled spring 43. The brake-shoe 42is normally, or while the machine is in operation, latchcd out ofcontact with the pulley-flan ge. Connected tov thefree end 0f thebrake-shoe is a vertical bar 44 which extends downward and is supportedand guided by a bracket 45 extending from the frame of the machine.

Adjustably secured to one side of this bar ,said movable bar 47 is movedrearward by any suitable means, the bar 44 is thereby unlatched and ispulled downward by the spring 43, thereby forcing the brake-shoe intocontact with the flange of the pulley 30, thereby stopping the feed ofthe fabric. i In the machine shown means are provided vforIautomatically throwing out the clutch 40,

and for automatically applying the brake 42, which means will behereinafter described.

The means Vfor releasing the brake and starting the machine to feedforward the fabric after the machine has been stopped land the brakeapplied will be next described.

A foot-treadle 49 extends across the front of the machine where it maybe conveniently operated. This treadle is secured by means ofvarms 50oneonl each side of the machine, to a rock-shaft 51, which extends acrossthe machine and is arranged to turn in bearings in the frame. Connectedto this rock-shaft are two weights 52, one on each side of the machine,which act tonormally hold the treadle 49 in its upper position. Securedto the rock-shaft 51 vis an arm 53, to which is connected one end of aconnecting rod 54, the other 'end of which rod is connected to one armof a bell-crank lever 55 which is pivoted on the frame. The other arm ofthis bellcrank lever is provided with a friction-roll l result will beto lift the brake-shoe 42 out of contact with the flange of the pulley30 and thus release the brake.

Connected to rthe arm of the bell-crank lever 55 to which the rod 54 isconnected is another connecting-rod 57, the opposite end of which isconnected to one arm of a bellcrank lever 58, which is pivoted on abracket 59 projecting from the frame of the machine. rEhe other arm ofthe bell-crank lever 58 is connected by a link 60 with the lower end ofthe clutch-lever 41. When, therefore, the treadle is depressed and thebell-crank lever 55 is rocked, the further result will be that thebell-crank lever 58 will be correspondingly rocked, and this in turnwill serve to ypull inward the lower end of the clutch-lever 41 and.thus throw in the clutch 40 and connect the pulley 22 to thedriving-shaft 19. Pivoted to the clutchlever 41 is a latch-bar 61,provided with a shoulder 62, adapted to engage a bracket 63, through aslot in which bracket the end of the latch-bar 61 extends. When l*theclutch 40 is thrown in to connect the pulley 22 with the shaft 19, theupper end of the clutch-level' 41 is moved away from the bracket 63, andso as to draw the latch-bar 61 outward and into a position where theshoulder 62 on said latch-bar will engage said bracket, and therebylatch and hold the clutch in its engaged position. The weight of thelatch-bar 61 will ordinarily be suflicient to cause said bar to falldown and engage the latch. If desired, however, a spring may be employedfor this purpose.

It is desirable in machines of this character to provide means toreverse the machine and the feeding of the fabric, in order that if theknife should fly out of the race, or any other accident happen, thefabric may be run back a short dist-ance for the purpose of reinsertingthe knife in the race. This reversal of the machine is effected by meansof the cross-belt 26 running on one of the steps of the cone-pulley 27on the drag-roll 13.- This cross-belt 26 is operated by the pulley 25which is loose on the main drivingshaft 19, but which is provided with aclutch 64 adapted to be operated by a. lever 65 for clutching saidpulley to said driving-shaft.

The means for operating this clutch 64 are as follows: Pivoted to theframe of the machine at the forward end thereof is a handlever 66, thehandle of which is in convenient position to be grasped by the operator.The lower end of this lever is connected by a link 67 to an arm 68projecting from a rock-shaft 69 which extends across the machine and ismounted in bearings in the frame. The lower end of the arm 68 isconnected by a Vlink 70 to one arm of a bellcrank lever 71 which ispivoted on a lbracket 72 secured to the frame of the machine. The otherend of this bell-crank lever 71 is connected to the lower end of theclutch-lever 65, which clutch-lever is pivoted at its other end to theframe. With this construction, as will be seen, when the upper end ofthe hand-lever 66 is pushed rearward, the result will be, through theoperation of the connecting parts, that the clutch will be thrown in andthe pulley 25 thus connected to the driving-shaft 19, and so as to drivethe dragroll 13 in the reverse direction.

As when the machine is stopped the brake is on, it is necessary wheneverit is desired to start the machine in the reverse direction that thebrake should first be thrown off. It is for this purpose that therock-shaft 69 is extended across the machine, and this rock-shaft isprovided 'at its opposite end with an arm 73 which underlies a frictionroller 74 on the vertical bar 44 which is connected with the brake-shoe42 which engages the flange of the pulley 30 on the drag-roll.Consequently whenever the rockshaft 69 referred to is rocked by pushingrearward the hand-lever 66, the rocking of said shaft will serve to liftthe brake-shoe 42' out of contact with the pulley-flange and thusrelease the brake. It is preferred to provide a certain amount of lostmotion in the connection between the lower end of the arm 68 and thelink 70 in order to insure that the brake shall be released before thereversing-clutch is thrown in.

The purpose of thetwo idler-rolls 12 and 15 is to hold the fabric up incontact with the drag-roll 13 and the feed-roll 14 respectively. 1t isdesirable to maintain the axis of each of said rolls 12 and 15 parallelwith the aXis of its companion roll, and it is also desirable that thegrip on the fabric between the feed-roll 14 and its bindingroll 15, andthe grip of the fabric between the drag-roll 13 and its binding-roll 12,shall "be substantially uniform. 1n order' to secure these results themachine is provided with an equalizing device designed to maintain thetwo binding-rolls 12 and 15 in proper relation with the rolls 13 and 14'respectively.

Each of the rolls 12 and 15 is mounted in movable bearings, thesebearings being formed in levers 75, 7 6, pivoted one at each side of themachine. Referring to Fig. 2, which shows the two levers at one side oft-he machine, one for each of said rolls, it will be seen that the lever75 is pivoted to the frame of the machine at 77, and that the lever 76is similarly pivoted at 78. The drag-roll 13 is mounted in one arm ofthe lever 75 and its companion lever on the opposite side of themachine, while the feedroll 14 -is mounted in one arm of the lever 76and its companion lever at the opposite side of the machine. Theopposite arms of the levers 75, 76, cross each other as shown.

-The free ends of said levers areyconnected by coiled springs 79, 80,with an equalizing bar 81. Connected to the center of, this equalizingbar is a cord 82 which extends around the pulley 83 located one on eachside of the machine, and is connected to the center of a correspondingequalizing bar 81 on the opposite side of the machine.

It will be `understood that the arrangement of levers, springs andequalizing bar is the same on both sides'of the machine. By thisconstruction the upward pressure of the two binding-rolls 12 and 15poduced by the four coiled springs referred to is equalized, and issuoli that the axis of each binding-roll will be maintained parallelwith the axis of its companion roll, and so that each binding-roll willalso be caused to grip the fabric uniformly throughout the length ofsaid rolls, provided of course the surface of the rolls are uniform andtrue.

The'means for'automatically throwing out the clutch 40 and forautomaticallyapplying the brake 42, and which means constitute anautomatic stop-motion adapted vto be operated by the bunch or seam inthe fabric will next be described. v In order'to stop the machine and toapply the brake so as to promptly stop the feed of the fabric, it isonly necessary to operate the, clutch-lever 41, the operation of whichlever, as above described, will serve both to throw out the clutch 40and to apply the brake 42. As above described, when the clutch-lever 41isoperated to throw in the clutch 40, said clutch and lever are latchedin engaging position by the latch-bar 61, or by the enga-gement of theshoulder 62 on said bar with the bracket 63. To the upper end of theclutchlever'41 is connected one end of a coil-spring 84, the other endof which spring is connected toa bracket 85 by means of an adjustingscrew 86.` Then the clutch-lever 42 is moved to engage the clutch 40,the spring 84 is put under tension, and said spring is held under suolitension by the engagement of the latch-bar 61 with the bracket 63. Inorder to throw out the clutch 40, therefore, it is only necessary todisengage said latch-bar 61 when the clutch-lever 41 will be moved bysaid spring 84 in the direction to throw out the clutch 40.

The means for automatically disengaging the lever G1 from engagementwith the bracket 63 are as follows: Extending across the machine abovethe fabric, whereby the fabric comes down the incline 8, is a rockshaft87 which carries a flat leaf-spring 88, which -spring likewise extendsacross the machine andnormally lies in engagement with vthe fabric.`

Pivoted to the bracket 89 is a lever 90 provided at one end with aprojection 91 adapted to be engaged by a latch formed on the end of thearm 92 carriedv by the rock-shaft 87. The opposite end of said lever isconnected by a link 93 with an arm 94 carried by a rock-shaft95-suitably mounted in fixed supports. The rock-shaft 95 is providedwith an upwardly projecting arm or toe 97 arranged to normally underlieone end of a pivoted lever or tappet 90 pivoted on the bar 47. Thetappet 97 is provided with a notch 97a adjacent to the toe 9G when theparts are in normal position.

Pivoted on the frame at 98 are two levers 99 lying side by side.y As theconstruction and operation of these two levers and their connecting andcooperating parts are the same, it will be sufficient to describe theconstruction and operation of one of said levers.

Mounted on the shaft of the driven roll 10 is an eccentric 100 which isconnected with the upper end of the lever 99, whereby said lever isvibrated back and forth at each revolution of said shaft.

The bar 47 before referred to extends lengthwise of the machine, saidbar being pivotally connected at one end to the pivoted link 101, andbeing pivotally connected at its other end to one arm of a bell-cranklever 102. Said bar 47 is thus capable of a lengthwise swinging movementand is adapted to operate said bell-crank lever. The ta )pet 97 pivotedon said bar 47 is normally lield in a horizontal. position by theengagement therewith of the toe 96, and when thus held in a horizontalposition the forward end of said tappet will be out of the path of thevibrating lever 99. The other arm of the bell-crank lever 102 projectsthrough an inclined slot or cam-slot 103 in the latch-bar G1 nivoted tothe clutch-lever 4l.

The operation of the automatic stop-motion above described is asfollows: As the bunch or seam in the fabric travels down the incline 8it will serve by engagement with the spring-arm 88 to rock the shaft 87and the arm 92 and to thereby disengage the latch on the end of said arm92 from the projection 91 on the lever 90, which will permitl the rearend of said lever to fall, or if desired a spring 90a may be employedtopull downward the rear end of said lever 90 when the latch 92 isdisengaged. The resulting upward movement ofthe forward end of saidlever 90 will serve through the connecting link 93 and arm 94 to rockthe shaft 95, and so as to move the toe 90 from beneath the tappet 97,or to a point in line with the notch 97a in said tappet and so as thusto permit the rear end of said tappet to fall. This will cause theforward end of said tappet to be raised into the path of the lower endof the vibrating lever 99. As the lower end of said lever 99 movesrearward, the engagement of said lever with the tappet 97 willy causethe bar 47 to be moved rearward and so as to turn the bell-crank lever102. The turning of said bell-crank lever will, by the engagementof theend of said lever with the cam-slot 103, serve to unlatch the latch-bar61, whereuponthe clutch-lever 41 will be operatedby the spring 84 tothrow out the clutch 40 and thereby disconnect the pulley 22 from theshaft 19. As will be understood, whenever the clutch40' is thus thrownout by the operation of the clutch-lever, 41, the brake 42 will besimultaneously applied through the intermediate connections hereinbeforedescribed.

As above stated, two levers 99 and two tappets 97 are preferablyemployed. The purpose in thus employing two levers and two tappets is toinsure greater promptness in stopping the machine. Thus with theeccentrics 100, which operate the levers 99, set opposite to each other,the lower ends of said levers will always be moving in oppositedirections, and so that one of said levers will always be moving in adirection to engage its tapnet.

It is desirable that means shall also be provided for stopping themachine by hand, which means will next be described. Connected to therock-shaft 87 at the opposite or right hand side of the machine is anarm 104 the lower end of which is connected by a connecting rod 105 withan arm 106 sel cured to a rock-shaft 107 suitably mounted at the frontof the machine, and which eX- tends across the machine. Projectingrear.` wardly from said rock-shaft is a plate 108 which preferablylikewise extends across the machine, and so that it may be convenientlyreached by the operator fromany point at the front of the machine.

In order to increase the sensitiveness o f the automatic stop-motionabove described, it is preferred to support the rear yend koftheconnecting rod 105 independently of the arm 104, and so as to relievesaid arm of the weight of said connecting rod` As shown' in thedrawings, the rear end of said connecting rod 105 is supported by a link109, one end of which link is pivotally connected to said rod 1.05, andthe other end pivotally cionnected to the frameor to a bracketfthereon.

In order that the automatic stop-motion may operate without having tomove the connecting-rod 105 and the parts connected therewith, lostmotion is vlprovided between the arm 104L and the rod 105, and for thispurpose the rod 105 is provided with a slot 110 in which the pi1r111'onthe lower end of the arm 104 works. A spring 112 is connected to the endof the rod 105 for returning said rod and the parts connected therewithto their normal position when they have been operated by hand, and aseparate spring 113 is connected to the arm 104 to 'return said arm, andthe parts connected therewith to their normal position when they havebeen operated either by hand or automatically. Means are also providedfor automatically resetting the parts of the stoplnotion mechanism whichmeans are as follows: Secured to theframe is a bracket 114 having yaprojecting arm which lies 1n the path rof the pivoted tappet 97, and therear end of said tappet is beveled, so that as the bar 47 movesrearward, the beveled end of the tappet, coming in contact with the armof the bracket 114, will cause said tappet to be lifted, thus liftingthe notch 97 a clear of the toe 96.

Adjustably secured to the rear end of the lever 90 is an arm 115carrying at its lower end of a roll 116. The latchbar 61 is provided onits upper edge with a cam-surface 117 .with which the roller 116 is keptin contact by the action of the spring 90e. When the latch-bar 61 isunlatched and the upper end of the clutch-lever 41 is moved inward bythespring 84, said latch-bar 61 will likewise be moved inward, which willcause the roll 116 to ride up the cam-surface 117, which will cause therear end of the lever 90 to be moved upward and the forward end of saidlever downward, which through the link 93 and arm 94 will serve to rockthe shaft 95 and so as to return the toe 96 to its normal positionbeneath the tappet 97, the rear end of which tappet has in the meantime.been raised,I i as above described. The several parts of Mthe automaticstop-motion will thus be automatically reset and so that said parts willbe restored to their proper positions for the next operation oftheautomatic stopmotion without the necessity for any hand manipulation;
